We don’t just go with the flow, we create it.

Pump Basics What are we talking about Our focus has been to educate and make our distributors aware of our MP Pumps, Inc. products, markets, and applications. This webinar has come about from the feed back we have received from you our distributors. –Key terms and definitions –Application Data –Pump Curves –Beyond the pumps –Trouble shooting –What’s new

Pump Basics Key Terms and Definitions Flow- liquid volume capacity of a pump stated in gpm or gph Head- measure of pressure expressed in feet. Indicates the height of a column of water being lifted by a pump (neglecting friction losses in the piping) Total Head- sum of discharge head, suction head, and friction losses Atmospheric Pressure- 1 psi = 2.31 ft of water Suction lift- Occurs when the liquid source is lower than the pump. Pumping action creates a partial vacuum and atmospheric pressure forces liquid up to the pump

Pump Basics Key Terms and Definitions NPSH- amount of atmospheric pressure available to push the liquid into a pump. –NPSHa –NPSHr Specific Gravity- the ratio of the weight of a given volume of liquid to the same volume of pure water. –Water is 8.3 lb./gal. Viscosity- the thickness of a liquid affecting its ability to flow. Cavitation- the rapid formation and collapse of vapor pockets (bubbles) in a flowing liquid in regions of very low pressure

Pump Basics Application Data Understanding these terms will help us to properly apply centrifugal pumps in applications brought our way. Keys to accurate pump application –Gather as much data as possible –Asking the right questions –Doing the research that may be necessary –Using available tools –Accurately apply the data given

Pump Basics Application Data Sheet

Pump Basics Asking the right questions Start at the beginning –Flooded suction or lift condition Lift required –Application fluid Temperature Solids Abrasive Concentration –Flow and head required Pump speed

Pump Basics Asking the right questions Drive requirements –Pedestal or Pumpak –Electric motor/Engine/Hydraulic –Horsepower restrictions –Voltage/Hertz requirements –Enclosure requirements Metallurgy –Cast Iron/SS/ Bronze/NiBrAl

Pump Basics Asking the right questions Mechanical seal requirements –Standard is carbon/ceramic/Viton –Chemical compatibility –Abrasive fluid –Single or double seal Using the Pump Curves –Speed –Impeller Trims –Priming Lines –NPSH –Efficiency

Pump Basics Pump Curves

Pump Basics Pressure and Temperature limits

Pump Basics Other Key Considerations Specific Gravity- effects the HP requirements required for the pump to obtain a given duty point Viscosity- the resistance to flow may effect the flow, head, and efficiency for a given application –Viscosity correction factors from hydraulic handbook –Open vs. Closed impeller Flanged vs. Threaded connections Minimum flow- not less than 10% of BEP

Pumps Basics Where to find important information Our website: You can find: Sales literature Product data sheets Performance curves Exploded view parts drawings Pricing information How to videos Webinar slide presentations

Pump Basics Beyond the pumps Instrumentation –Can play a key role in quickly diagnosing pump performance issues Pressure gages Flow meters –Timed tank level readings –How long does it take to transfer the product Temperature gages Isolation valves

Pump Basics Troubleshooting Self-priming pump priming issues: –Was pump filled initially –Impeller to wear plate clearance –Check valves in the discharge line –Duty point beyond the lift capability of the pump –Direction of rotation –Clogged suction line –Air leaks in the suction side –If hose is used is it rated for suction use

Pump Basics Troubleshooting Mechanical seal failures –Did the pump run dry –Correct impeller to wear plate clearance sets the correct seal working height –Incorrect application for materials of construction –Abrasives –Selected materials correct for the chemical concentration

Pump Basics Troubleshooting Pumpak installation –Shim material provided in the pumpak from the factory –Shim material maintains the proper impeller clearance during assembly –Number one reason for incorrect setting of the impeller clearance is that the shim material is removed prior to mounting the pumpak –Incorrect impeller clearance can lead to inadequate performance and shortened seal life
